. 4 Claims. My invention relates to novel'apparatus for Y andmethods ofmanufacture of paper,` orcardcard boxes,corrugated or otherwise," andmore particularly, .to novel apparatus for and methods L5, ofmanufacture ofsamples of paper or cardboard boxes. v f The object of myinvention isV to provide a single machinewhich will `do the workof'scoring and trimming, slicing, cutting and blocking required in themanufacture of cardboard boxes vwhich in the past required severalmachines `to accomplish. Y

Another object yof my invention isV to provide means for performing theabove-mentionedoper- 1.5, ations by the use of power driven machineryand on a mass production basis as againstfthe hand operate-d mechanismsthat were used in the past in the manufacture of sample cardboardboxes.V

Another objectof my invention is to provide motive powers may beconnected with or detached from any one or several mechanisms in such amanner as'to Vmake the various mechanisms operate either singly Vor`jointly or in any desired combination whatsoever. There are otherobjects of my invention `which together with the foregoingV will appearinthe detailed description which is to follow in connecwhich: Figure 1shows a longitudinal perspective View of a preferred'type of thismachine."V

Figure A 2 shows- 'a longitudinalV cross-sectional View of themachine,its various parts, and their location with respect to each other; Fig. 3is an end View in. elevation lookingfat 35 the left of Figure l, showingthe circular scorers and trimmers.

' Figures 4 and 5 show boardv blanks and the may be scored,V creasedilar machines. ReferringV now vmore particularly tol Fig. 1,- a metalframeV serves asa support for the various mechanisms as well as for thetable topl 2 upon are processed. l f In carrying out my invention inconnection with a blank such as shown in Figure 4,V I first trimthe'edges 3 and tewith shears 5 (Figure 1). These shears 5 aremanipulated by hand, a blade 6 which .is 'secured Yto a handle 'I byVmeans of a number of bolts Il, and iwhich can be removed from time totime for the purpose of sharpening. The otherrblade of the shearsconsists of a steel bar I2 (Figure 2) Vwhich to top 2 of the table and-various froms of cardmanner in which fthey and cut Vby this and sim-(chier-11| g forms, a Vsharp edge I3. As the blank is laid on table; 2it is gauged by means of scale I4 and held ini place underbar |5 whichis pivoted at hingel'and travels in yoke I9.

VWhen necessary, scaley |4 can be extended beyond the table throughextensionsV ifi and I8 whichVV `can be fed Vout from under the tablethrough hand wheel 2|. This wheel turns rod 22 on which are mountedgeared wheelsY 23, 24 at the bottom of exwhich engage similar teethtension bars I1 and I8 and propel them forward. Bars I1 and |8'arejoined by angle 25 which acts as a stop for they blank. To facilitatethe operation of the shears,ra counterweight 26 is placed on the far endof Vthe shears beyondthe pin 27. Edge 4 of theblank is trimmed in thesame manner as was edge 3; after which theblank is ready for the bodyscores'l Shown in Figure 4. The body score is made through creaser orscorer 3.2,v which operates through eccentric straps33 pivoted on shaft34.4

VOn one end of shaft 34 is mounted wheel 35 'which'V drivesY member 4|vertically in slot 42 formed by the standards or guides 43. Member Y 4|terminates in a rounded blade 44.

When Ybody scores 3| are to be made,V the blank is so adjusted alongscale I4 that blade-44 will be exactly above the line to be scored. Aslight pressure of the foot on pedal 45 will operate rod 46, which actsYupon clutch (not shown) thus connecting eccentricstraps 33 with theVmotive power. Scorer 32 comes 'down upon the table and the cardboard isscored between blade 44 and groove 47 in top -2 of the table.

The blank is now moved farther to the left Aand fed under the rotaryscorers and trimmers whose function itis to trim the edges 5| and 52 ofthe blank in Figure 4 and to produce the ap'scores 53 and 54. Y l

The rotary scorers and trimmers consist of an upper shaft 55 and a lowershaft 56. Upon these shaftsV are adjustably mounted upper trimmingknives 511 and lower trimming knives 6|, also upper scoring wheels 52and lower scoring wheels 63.

The lower shaft 55 derives its motion from pulley 64 (Figure 2) which isdriven by belt 65 riding on pulley 56 whichin turn derives its motionfrom motor 36 through pulleys 35 and 3T and belt 33.

, Wheny necessary, shaft 56 ,can'be disconnected from the source ofpower by means of hand operatedclutch handle' 61 controlling a suitableclutch in the usual; manner (clutch not shown).

It can also be operated by hand through wheel 68.

Shaft 5E imparts motion to shaft 55 through a pair of sets of gearslocated on the shaft at frame 1I. When it is required to disengage theupper shaft 55 from the lower shaft 56, a handle 12, Fig. 1, is turnedone quarter of a revolution. This handle is rigidly connected to a rod13 resting in bearings 14. Securely connected to rod 13 are cams 15,which press upon the top of the frame 1I when handle 12 (Figure 1) isturned and lifts shaft 55 a distance sufficient to disengage it fromshaft 56, thus permitting the blank to be moved about freely between therollers without fear of being scored or trimmed.

The next process is that of blocking or angle cuts. For this purpose,two separate motors 16 and 11 are provided. Motor 16 is mounted onadjustable platform 8| which is fastened to frame I. Motor 16 isconnected to a gear 82, (Figure 1) from which projects an eccentricallylocated pin 83. Pivoted on pin 83 is one end of an arm S4, the other endof which slides in a vertical groove in guide 85, and is at the sametime connected to a triangular cutting block 86 to which it imparts upand down motion. The sharp edge of the cutting block meets a similarlyshaped cutting edge 81 on the level of the table, and the two effect a90 degree cut-out of any desired depth in the blank. Gear 82 isconnected to and disconnected from motor 16 by means of a clutch 8Bwhich is operated by the pressure of a foot on pedal 89.

When a rectangular cut-out is required, the motor 11 is used. Theoperation of motor 11 is similar' to that of motor 16. It is mounted onan adjustable platform 9|, (Figure 2) which fastens to frame l Motor 11is geared to 92 from which projects an ecoentrically located pin 93.Pivoted on pin 93 is one end of arm 94 and is at the same time connectedto` a rectangular cutting block 96 to which it imparts up and downmotion. They edge of cutting block 95 meets a similarly shaped cuttingedge 91 on the level of the tableand the two effect a rectangular cutoutof desired length and breadth in the blank. The connection of wheel 92to motor 11 is controlled by means of clutch 98 which is operated by thepressure of a foot on pedal 99.

For convenience in handling the blank during the blocking process, apanel I0! forming part of top 2 of the table has been placed on hingesH52 in order that it may be dropped, and the operator be allowed to workwithin closer range of the cutting blocks 85 and 96.

Although I have disclosed for purposes of illustration one form of myinvention, it will be obvious that it may take other forms than thatherein described, and I do not intend to be limited except as set forthin the appended claims.
